Spring Cage Installation Terminal Blocks
STI 2,5 and STI 4
The asymmetrically arranged terminal foot makes
the STI series stand out against standard terminal
blocks. This foot makes it possible to route the neutral
busbar past the terminal strip and to fix it in the
insulated supports. The neutral busbar makes contact
via the screwless neutral-disconnect slide by simple
levering with a screwdriver. Considerable space
savings in the control cabinet can be made by using the
"mini-spring" spring cage system, without having to
give up the familiar high quality features such as the
generous labeling option, maximum connection space
and the flexible plug-in bridge system.
Assembly
In order to achieve a reliable contact between the
disconnect slide and the neutral busbar, the AB-STI
supports must be mounted at the beginning and end of
each terminal strip or, in the case of longer terminal
strips, approx. every 20 cm.
